MAN D4276 @ Agritechnica 2019

MAN D4276 is still ready for farming. After the preview at last Bauma in Munich, the 16.2 liters engine D4276, with 142 mm bore and 170 mm stroke, confirms that MAN believes in diesel engines, especially for the heavy-duty applications.


Following the main features of the German engine block, which in Hannover is a natural candidate for large harvesting machines. As we wrote in the article on Agritechnica, it was chosen by AGCO Corporation for the Ideal 10 combine harvester. 581 kW at 1900 rpm, weighing 1,280 kg, this power pack is the most powerful inline six-cylinder engine for agricultural machines that MAN Engines has ever developed. This peak output has been achieved by MAN Engines as a result of its newly developed charging concept with fixed geometry charger, which enables a maximum torque of 3,400 Nm between 1,350 rpm and 1,600 rpm.

MAN Engines D4276

Reiner Rössner, Head of Sales at MAN Engines

«With the D4276, we are offering OEM manufacturers an engine that is easy to integrate and will help set them and their machines apart from the competition, thanks to its unique performance characteristics,» commented Reiner Rössner, Head of Sales at MAN Engines. To comply with current emission levels, the D4276 relies on the compact, flexible and modular exhaust gas aftertreatment (EGA) system from MAN Engines, and will be available for the main markets in models meeting the EU Stage V and EPA/CARB Tier 4 emission standards.


The D4276 is based on the modern D3876 engine series, Diesel of the year 2016, which is already successfully established on the market, but has been systematically developed to meet the increased performance demands of heavy applications in agricultural machinery. To achieve this, it was necessary to further improve the already outstanding power-to-weight ratio of the D3876. This meant expanding the bore by four millimetres from 138 mm to 142 mm, which had the effect of increasing the displacement from 15.3 to 16.2 litres.

MAN D4276 and the modification of the common rail

A modification of the Common Rail injection system provides the necessary increase in fuel supply. The use of a fully redeveloped high-pressure pump generates supply quantities up to 40 percent higher while vibration loads and noise emissions remain constant. Diesel injectors that have been further developed especially for the D4276 with improved flow and high injection pressures of up to 2,500 bar ensure an ideal degree of fuel atomisation and penetration. This results in low-emission, low-soot combustion combined with more favourable levels of fuel and AdBlue fluid consumption.
